An improved method for scalability issue in wireless sensor networks

The property of scalability for a given system indicates the ability of a system or a subsystem to be modified with changing load on the system. For a sufficiently large complex system, there are several factors that influence the ability of the system to scale. It is necessary to incorporate solutions to these factors (or bottlenecks) in the design for scalability of a given system. Sensor networks have all the basic features of ad hoc networks but to different degrees - for example, much lower mobility and much more stringent energy requirements.The design principles to handle the key factors that influence the scalability of large complex systems are explained further. Protocols can support simple, innovative, and relatively less expensive methodology to guarantee that a large complex system (such as network of sensors) is scalable under varying load conditions. These sensor networks connect large numbers of independent sensor nodes to make measurements of interest over a geographic region. Because of their small physical size and low cost, sensor nodes have a number of constraints in their operation: they have limited processing ability, limited storage on the node itself, and limited power. A sensor network system and protocol design aims to reduce and optimize the power usage of sensor nodes. Here the current state of research and evaluate open issue scalability in development of scalable wireless sensor networks is analyzed.
